-ful Improvements in a Railway-Car Construction, of which the followingis a specification. I

This invention relates to railway car construction.

As clearly set forth in some of my'recent patents, for example, PatentsNumbers 1,300,959,-.1,300,960, 1,300,961, and 1,300,962, granted April15, 1919, and 'Number 1,304,969, granted May 27, 1919, a great deal ofimportance is given to the question of increasing the carryingcapacity-of railway cars, and particularly dump .cars. In theabove-mentioned patents it will be seen that the capacity of the carshas been increased. greatly by changingthe floor construction oyer thetrucks. a

In this present case'it is 'mypbject to further increase the capacity ofsuch cars, and at the same time give added strength to the carsides,presenting a simple, neat and inex-' pensive construction adaptedto meet the various requirements for successful commercial use.

These and other objects are accomplished the car sides are spaced apartthe maximum allowed'amount, and at the ends thereof provided with aplurality of corrugations for giving strength thereto, and providingladder rungs adjacent the corrugations whereby said ladder is maintainedsubstantially within the vertical confines of the car sides.

The invention is illustrated on the a'ccompanying sheet of drawings, inwhich Figure 1 is a fragmentary side elevation of a railway oarembodying my invention;

Fig. 2 is a sectional view taken in the. plane of line 2-2 of Fig; 1;

Fig. 3 is a fragmentary sectional view taken in the plane of line 3-3 ofFig. 1; and

Fig. 4 is a sectional view taken in the plane of line 4-4 of Fig- 3.

As is well known, the over-all dimensions of railway cars must be withinpredeter mined limits to meet all clearance conditions. To design a carin accordance with clearance conditions and at the same time increasethe carrying. capacity thereof an appreciable amount, is a roblem towhich I have given considerab e attention. As

-mentioned above, the carrying capacity of cars has been increased.greatly by improving the floor construction over the car trucks, itbeing assumed that the car sides were spaced the maximum alloweddistance. .111

cars now in use the ladders at the sides thereof extend outwardly fromthe car sides a considerable amount, thereby limiting, in accordancewith clearance conditions, the distance the car sides may be spaced. Inthis present case I have spaced the car sides an increased amountcommensurate with the distance the ladders extend outwardly from eachside of the car and have providedthe sides of the cars at the endsthereof with corrugations, adjacent to which ladder rungs are placedwhich lie substantially within thevertical confinesof the side of thecar,

thereby increasing the carrying capacity of the car and also'increasingthe strength of the sides of tlm car and at'the same time presenting aladderconstruction which is simple, neat in appearance, and'relativelyinexpensive.

Referring'to the figures of the drawings,

it will be noted that the car has sides 10,

ends 11, and a floor 12, the car sides 10 sub stantially throughouttheirentire length being spaced apart the maximum allowed amount. Thecar sides 10 at the ends thereof are provided with corrugations 13, thedepth of whichincreasesdownwardly from 1 a zero point 14 coincidentwith'the side of the car to a point 15 of-maximum depth, from which thecorrugation rapidly decreases to the next underlying zero point 14.Adjacent the deepest portions of the, corrugations, ladder rungs 16 areprovided which aresecured to'the car sides, and it will be noted thatthese ladder rungs lie substantially within the verticalconfines of thecar sides. The upper ladder'rung 17 extends outwardly a slightly greaterdistance to compensate forthe relatively shallow corrugation 18 adjacentthereto. In climbing'up or down the ladder, it is simply necessary forone to maintain the toe in constant contact with the. corrugated portionand slide the foot downwardly, whereby the foot will be guided in amanner to make the footing safest, the footpassing into the corrugationsin accordance with the depth thereof.

The lower ladder section- 19 may be of the usual type and arranged inits usual manner. By providing the ends of the car sides with corrugatedportions, it is not necessary to offset the top member 20 of the carsides at the ladder portion thereof.

It is my intention to cover all modifications of the invention fallingwithin the spirit and scope of the following claims.

I claim: 1. A railway car having sides, ends and a floor, the sidesbeing spaced apart the maximum amount to increase the carrying capacityof the car, said sides having a plurality of corrugations formedtherein, and ladder rungs secured to the car sides opposite thedepressed portions of said corrugations and extending lengthwise beyondthe ends of the corrugations.

2. A railway car having sides, ends and a floor, the sides being spacedapart the max mum amount to increase the carrying capacity of the car,said sides having a plurality of corrugations the depth of which varies,

' and ladder rungs secured to the car sides adjacent the deepest portionof said corrugations.

3. A railway car having a body portion including a side withcorrugations formed therein, and ladder rungs secured to saidcar sideadjacent the deepest portion of said corrugations.

4. A railway car having a body portion including a side with a pluralityof tapering corrugations formed therein, the corrugations increasing indepth from a point coincident with the outer surface of the car side,and ladder rungs secured to the car side adjacent the deepest portion ofsaid corrugations.

5. A railway car having a body portion, said body portion including awall with corrugations formed therein and ladder rungs secured to saidwall adjacent the ends of the depressed portions of said corrugationsand extending lengthwise thereof.
